<p>I understand that cargo captures the stdout and stderr output of the rustc it invokes, but reading cargo's docs and book I can't find a good explanation. <br>
I'm modifying rustc's diagnostic logging in my custom toolchain but nothing comes out, regardless of RUSTC_LOG's setting. <br>
I can just invoke rustc directly as usual, but I just wanted to know why this happens.</p>

<p><span class="user-mention" data-user-id="209053">@Iñaki Garay</span> it's probably cached the lack of output</p>
